Are you on any ROMS? If so that may be the issue if it still shows in the notification after the call ends.

I have the stock ROM but my phone is rooted. Recently I did install Xposed Installer with 4 modules (Tinted Status Bar, Wanam Xposed, Xposed LED Control, and YouTube AdAway). I've looked through all their settings but can't find what could be causing my issue.

One of those may be causing the issue, try unintalling them and see if it fixes the issue.
